Use GKE-specific metrics in the proxy

Browse source 
Associate the custom metrics with the correct monitored resource type. The labels of the monitored resource are either obtained from environment variables for the container, configured in the GKE deployment file, or queried from GCE metadate server. Using the correct monitored resource can help performance and reduced out-of-order metric writes.

Also changed the metrics display name to be more descriptive.
